I just purchased a used P22 (gun only, nothing else included). I did a routine field strip in order to clean and lubricate it before I took it to the range to test it out. Using a downloaded PDF file, i read and followed the diasassembly instructions, cleaned and oiled, THEN read the assembly instructions. Ruh-roh. It seems that, in order to install the recoil spring, a certain tool is required and I don't have the tool. I tried a dowel and a small screwdriver, to no avail. It seems I need that tool. I've Emailed customer support, but no reply as yet. Anybody have any other tips on how to install that dratted spring? (GLOCKs is sooooo much simpler).
